Abstract

The purely hydrodynamical behaviour of collapsing stellar core is investigated. Adiabaticity and spherical symmetry are assumed. The equation of state consists of a high and low density branch. Both branches are parametrized by constant adiabatic indices. The evolution of the collapsing core is examined for various parametrizations of the equation of state. Emphasis is placed upon seeking parametrizations favouring mass ejection. No mass ejection occurred for any parametrization considered. However, behaviour most suggestive of mass ejection was observed in those models where the adiabatic index rapidly changed from slightly below 4/3 to slightly above.
